Answer:

  78°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relations between angles and sides of a right triangle. In particular, ...

  Cos = Adjacent/Hypotenuse

  cos(F) = FG/FE = 1.5/7.5 = 0.2

The inverse cosine function is used to find the angle:

  ∠F = arccos(0.2)

  ∠F ≈ 78°

Rachel works at a bookstore. On Tuesday, she sold twice as many books as she did on Monday. On Wednesday, she sold 6 fewer books
laila [671]
Let, the number of books on Monday = m
On Tuesday = 2m
On Wednesday = 2m - 6

Equation: m + 2m + (2m - 6) = 19
You can solve it:
5m = 19 + 6
m = 25/5
m = 5

In short, He sold 5 books on Monday

Hope this helps!
